Infineon Technologies S25FL032P0XBHI020

Overview

S25FL032P0XBHI020 from Cypress Semiconductor is a 32-Mbit, single-power-supply SPI Flash memory with uniform 64-KB sectors, 4-KB/8-KB sub-sectors, 256-byte page size, and Quad I/O FAST_READ support up to 80 MHz (40 MB/s). It operates across 2.7–3.6 V, delivers 100,000 program/erase cycles per sector, and retains data for 20 years. Used in embedded boot code storage for industrial controllers requiring secure, field-upgradable firmware.

For engineers reviewing the S25FL032P0XBHI020 datasheet, S25FL032P0XBHI020 pinout, S25FL032P0XBHI020 application, or S25FL032P0XBHI020 equivalent, key selection criteria include SPI quad I/O timing compliance, OTP programmability for device ID, sector protection granularity, and industrial temperature range (–40°C to +85°C) operation.

Technical Context

The S25FL032P implements a serial peripheral interface with five extended command sets: Dual Output Read (DOR), Quad Output Read (QOR), Dual I/O Read (DIOR), Quad I/O Read (QIOR), and Quad Page Program (QPP). All high-speed modes use SI, SO, W#/ACC, and HOLD# as bidirectional I/O pins under clock control up to 80 MHz.

It integrates JEDEC-standard Device ID, Common Flash Interface (CFI) compliance, and a 128-bit factory- or customer-programmable OTP area with lock capability. Memory protection uses Status Register BP2–BP0 bits and W#/ACC pin assertion to enforce read-only access on configurable sector ranges.

FAQ

Is S25FL032P0XBHI020 recommended for new designs?

No. Cypress explicitly states this part is "Not Recommended for New Design" and recommends migration to S25FL064L. It remains available for legacy production and repair, with full technical documentation and known lifecycle status. Designers initiating new projects should evaluate S25FL064L for compatibility and enhanced features.

What package type does S25FL032P0XBHI020 use?

S25FL032P0XBHI020 uses a 24-ball BGA package measuring 6 × 8 mm with a 6 × 4 pin configuration (FAC024 footprint), lead-free and low-halogen compliant, rated for industrial temperature range (–40°C to +85°C).

Does this device support Quad SPI mode with hardware write protection?

Yes. It supports Quad I/O High Performance Read (QIOR) and Quad Page Program (QPP) using SI, SO, W#/ACC, and HOLD# as bidirectional pins. Hardware write protection is implemented via W#/ACC pin assertion combined with Status Register BP2–BP0 bits to lock specific memory sectors.

Can the OTP area be reprogrammed after locking?

No. The 128-bit primary OTP region can be programmed once and permanently locked using the LOCK instruction. Once locked, it cannot be rewritten or erased. The additional 490-byte OTP space supports multiple programming cycles until explicitly locked, but locking is irreversible.
